Kylie Jenner on the Difference Between "Baby Blues" and Postpartum Depression

In the last season of Hulu show "The Kardashians," Jenner spoke with her sister Kendall about her mental health roughly a month after giving birth to her son.

Kendall asked, "How are you? How's the baby?," to which Jenner candidly replied, "It's been really hard for me." She went on to describe crying nonstop for the first few weeks postpartum to the point where she'd experience crippling headaches. "It's just the baby blues, and then it kinda goes away."

She even went out of her way to describe the difference between the baby blues and postpartum depression, which is mainly that the former only lasts about six weeks. "After about six weeks, I started to feel better, but I definitely had the case of the blues."
